Italian Polini Launches Mid-Motor for E-Bikes
BERGAMO, Italy – Renowned Italian scooter and motorcycle component supplier Polini is the next to enter the e-bike market and presented a mid-motor drive system at last weekend’s Cosmobike show in Verona, Italy.
The Polini E-P3 has been completely designed and developed by Polini’s engineers. According to the company, “It stands out for its unique design, compact dimensions and lighter weight compared to the motors currently available. The mid motor weights 2,850 grams and the battery 2,500 grams.”
To make OEM assembly easier, the fitting of the mid-motor allows for universal, road, MTB front and MTB full-suspension variations. The 250 watt motor offers peak torque of 70Nm. The Polini system comes with 400 or 500 Wh batteries. The battery holder, specially designed to reduce the optical impact, is made of aluminium, and it is integrated in the motor mount.
To match a wide range of e-bikes Polini developed three different pedal axles at 136 mm, 142 mm and 157 mm for the E-P3. The system comes with a torque sensor, speed sensor and pedal frequency sensor.
Founded in 1945 as a small workshop for bicycles, Battista Polini soon rode the wave of the country’s thriving industrial development in the fifties. In their search for new solutions to ensure the engines better performance, Polini became trendsetting in the design and in the production of special parts for scooters and motorscooters. Today Polini is present in more than 64 countries.
